Abstract
The invention relates to a large-space four-stage explosion-suppression junction box. The junction box comprises a junction box base, an inner hexagon screw, a spring washer, a check washer, wiring bolts, terminal sleeves, screw caps, a junction box cover and a junction box hopper, wherein the junction box cover is arranged above the junction box base in a threaded connection way; the junction box hopper is mounted on the junction box cover; the large-space four-stage explosion-suppression junction box is characterized in that the junction box base is mounted on the machine base through the inner hexagon screw and the spring washer; the spring washer is arranged on the inner hexagon screw in a sleeving manner; the junction box base is connected with the multiple terminal sleeves; the check washer used for sealing and tightening is arranged on the terminal sleeves in a sleeving manner; the terminal sleeves are arranged on the multiple wiring bolts in a sleeving manner; and the wiring bolts and the terminal sleeves are fastened through the screw caps. The large-space four-stage explosion-suppression junction box is widely applicable to explosion occasions with combustible gases with the ignition temperature groups of T1 to T4; and meanwhile, the junction box is simple in structure, larger in space, and more convenient to operate, so that a user can use the junction box in a more comfortable and safer manner; and the operation of a motor is safer and more reliable as well.
Description
Technical field
The present invention relates to a kind of explosion-proof connection box, especially large space level Four explosion-proof connection box, it is adaptable to the environment that easily set off an explosion containing hydrogen or acetylene or its mixed gas etc..
Background technology
Flameproof motor progressively develops into today, and anti-explosion terminal box is as one of most important key link of motor, and particularly in having the environment of hydrogen and acetylene, safe and reliable is very important.Requiring the explosive gas mixture explosion time of motor interior, flameproof enclosure should not damage or produce the change affecting explosion insulation performance；Internal explosion flame does not allow the flameproof joint by shell to cause the blast of extraneous explosion admixture of gas.
At present, traditional Construction of Flame-proof Terminal is narrow and small due to inner space, electric clearance and creep age distance that outside lead wire is mutual reduce, make motor running unreliable, and flame proof gap and flame proof effective length do not reach the requirement of ExdIICT1～T4Gb, the blast of the explosive gas mixture of external environment condition can be caused.In order to ensure flame-proof type motor in the environment having hydrogen and acetylene etc. easily to set off an explosion reliable, we go to design junction box structure according to actual manufacturing experience, meet the use environment having hydrogen and acetylene etc. easily to set off an explosion, make motor running safe and reliable.
Summary of the invention
It is an object of the invention to overcome existing defects in prior art, a kind of large space level Four explosion-proof connection box is provided, the novel structure of this explosion-proof connection box, sealing is strong, space is big, operation is convenient, and flame proof gap and flame proof effective length reach ExdIICT1～T4Gb, can ensure that the reliability of motor running.
For realizing above technical purpose, the technical solution used in the present invention is: large space level Four explosion-proof connection box, including junction box seat, soket head cap screw, spring washer, stop washer, connection bolt, terminal sleeve, nut, connector cover and rosette bucket, described connector cover is threadedly attached in above junction box seat, described rosette bucket is arranged on connector cover, it is characterized in that: described junction box seat is arranged on support by soket head cap screw and spring washer, described spring washer is enclosed within hexagon socket head cap screw, described junction box seat is connected with several terminal sleeve, stop washer for sealing and fasten is enclosed within terminal sleeve, described terminal sleeve is enclosed within several connection bolts, described connection bolt is fastened by nut with terminal sleeve.
As preferably, described junction box seat uses blind hole screw connection manner to fasten by hexagon socket head cap screw and spring washer with support.
As preferably, described terminal sleeve uses the mode being spirally connected to be connected with junction box seat.
As can be seen from the above description, the method have technical effect that: the rosette of the present invention and motor bed-plate use the fastening of blind hole screw connection manner and position to be arranged at below rosette, liberate the inner space of rosette, facilitate user's lead wire, the leader cable that sectional area is bigger can be selected, safety coefficient is greatly improved, and the space of terminal sleeve and junction box seat bottom is strengthened, workman is facilitated to assemble, operating the facility that more saves time, the explosion-proof connection box of this kind of structure can guarantee that the reliability of motor running.
